A main object of the invention is to provide an improved mechanicalmovement which may readily and properlr be adjusted in respect to someobject outsi c of the system Without varying the relations between themore important elements of the system.

A further object of the invention is to provide a simple, efficient andcompact adjusting mechanism which will permit instant and readyadjustment eve-n while the machine is running, and which can be easilyand readily operated by the operator with least effort and expenditureof time on his part and with a high degree of accuracy and with afineness of adjustment desirable on any high grade machine.

A still further object is to provide a simple and eiiicient adjustingmechanism whereby the, adjustment of the load shaft or one element ofthe mechanism with respect to a fixed outside point may be simply andeasily and effectively achieved Without affecting in any material mannerthe cyclical relations which exist at the time between the load shaftand the other elements within the system, such as another shaft. Inother` words, the motion of one shaft is not affected by the adjustmentof the other shaft.

Further and more specific objects, features, and advantages will moreclearly appear from the description given when taken in connection withthe accompanying drawings which form part of the specification and whichillustrate one present preferred form of the invention.

Briefly, the invention concerns the provision of a main driving shaftdirectly connected to one of the load shafts of the movement. This loadshaft is directly geared to a pin Wheel shaft of an intermittentmechanism of the machine with a governing fly wheel mounted on anddriven with the pin wheel shaft. The intermittent mechanism is disposedin a rotatable box or housing or frame which can be rotated so that thepin Wheel shaft moves around the center of the box in a predeterminedarc of movement. On the machineis another and practically similar box orhousing containing a shaft on which 1s a fixed gear. This latter shaftis located exactly the same distance from the center lof its box as 1sthe pin wheel shaftfrom the center of its box and moves in the same arc.Means are provided to connect the two boxes or housings so that as theone with the fixed gear is moved or rotated the other will be moved inthe same direction and to the same extent. The fixed gear on the secondhousing is m'eshed with4 a control shaft by means of a stralght rack ofthe cylindrical type and this control shaft is connected with the oneload shaft so that the movement of this load shaft as to turning orangular movement thereof is controlled. The mechanism which rotates oneor the other box or housing is so related and associated with the othermechanism that the pin wheel position may be changed and in so doing theposition of the associated star wheel and the other load shaft which isconnected to the star Wheel may be changed to adjust it regardingoutside fixed factors and this can be done Without changing therelarespect to the other elements `in the move.- ment.

The resent preferredvform 'of the mvention is illustrated in theaccompanying drawin which,

As shown in the drawings the present preferred form of the invention isapplied as a mechanical movement to a motion picture projector altho itmay be applied to any type of machine. It is shown as mounted on t ehead of the projector which has a central mechanism-supportingr wall orpartition 10. This apparatus comprises a main drive shaft 13 verticallydisposed and suitably actuated in a manner not shown. This drive shaft13 has thereon a ar 12 meshing with a gear 11 i 1' avide partly on aload sha 14.

wisdi The drive of the mechanism including the load shaft 14 and the oration of the intermittent mechanism an its adjustment for the purposeof fram' or adjustin the various parts are to be ereinafter escribed.Mounted on the partition in s aced relation are two boxes 26 and 27 preerably circular and rotatable and they are dis osed in suitable journals28 and 29 forme in the wall or partition 10. These journals 28 and 29are both open at the front and the rear and the boxes or rotatablemembers 26 and 27 aresnugly disposed thereon. As shown in Fig. 4 the box26 is chambered and rotatably receives a shaft 30 on one end of which isa pin wheel 31v of the usual intermittent mechanism. This pin wheelmeshes with a star wheel 32 mounted ona shaft 33 disposed centrally ofthe axis of the box 26 and journalled in a sleeve 34 on a plate 35fastened to a face of the journal member 28. Onv the other end of theshaft 33 there is fastened any suitable load or device. This shaft is asecond load shaft, the first one mentioned bethe shaft 14 abovementioned. mn the other end of the pin wheel shaft 30 d a ily wheel 36which regulates and sm es the motion of the intermittent mechanism. Aboa gear 37 preferably a worm is disped on thegshaft 30 adjacent theyawrheel 36. This worm gear 37 meshes with a worm 38 on the first loadshaft 14 above mentioned. The first load shaft 14 is drivenV directlyfrom the drive shaft 13 as above mentioned. Y The first load shaft 14 isjournalled at spaced points along its length in journal elements such as41, 42, and 43 which are disposedon one face of a plate 44. This plate44 is disposed across the face of the journals 28 and 29 and is resboxes .26 and 27. t is connected to the box 26, as seen in Fig. 4, bymeans of a headed pin shaft 45 suitably mounted on a sleeve 46 astenedto the box 26. The pin shaft 45 passes through a curved slot 49 in theplate 44, the diameter of the slot and the curvature -thereof beingequal to the distance between the pin wheel shaft and the center of theaxis of the box 26. It will also be noticed that the plate 44 issupported on a sleeve 50 which extends fromvthe box 26 and also acts asa journal for the. pin wheel shaft 30.

Referring now to the box 27, it will be seen especially in Fig. 7, thatthis box 27 is journalled in the journal element 29 on the head wall1'0. This box receives a shaft 51 which is fixed therein and cannotrotate independent of the rotation of the box 27. The shaft 51 has onone end a gear 52 fixed thereon. This gear meshes with a gear 53 on acontrol shaft 54. This shaft 54 is j ournalled on the plate 44 injournals 55 and 56 as seen in Fi 1 and 2. One end of the control shaft54 as an operating handle 57 thereon. The gear 53 is preferably a sti'aiht rack gear as shown. It will be observe that the control shaft 54 andthe first load shaft 14 are at different levels on the plate 44 althothey are both horizontal. It will also be noticed that the boxes 26 and27 are both of the same diameter and that the are of swing of the pinwheel shaft 30 and the arc of swing of i;

the shaft 51 are the same altho thc boxes are not at the same horizontallevel on the plate 44. Therefore when the box 27 is rotated, itsconnection withthe plate 44 will'.r0tate the box 26 and will swing thepin wheel 30 through the same arc as that through which the shaft 51 isswung by the movement of the box 27. The plate 44 is constrained to bedisposed against the face of the box 27 bv means of the headed pin shaft57 to hold theplate 44'in position and having a spring 58 between thesleeve 59 and the collar 60 on the inner end of this shaft 57. The pinshaft 57 passes through. a curved slot 61 in the P18-te 44 which slot issimilar in curvature 5"" and size to the slot 49 previously mentioned asdisposed in the plate 44. Also it will be observed that a sleeve 62extends from the box 27 through the plate 44 and acts further as asupport therefor. One face of the box 27 is provided with a dan e 63 thelower portion of which is provide with teeth 64 engaged by teeth on agear 65 on a shaft 66 j ournalled on the partition 10 and having ctivelyconnected to the end-operating handle 67 to turn it. When the I shaft G6is turned then the box 27 is,v rotated.

Referring to Figs. 1 and 2, it will be seen that the control shaft 54 isconnected to the irst load shaft 14 by means of a yoke member having amain body portion 68 and two 0pposite spaced legs orlimb portions 69 and70. The yoke 68 is held in position-on shaft 14 by means of set' screws71 which extend into a slight slot in the shaft 14 so that the yoke canbe slightly adjusted alongthe shaft 14 if desired. The yoke member 68 isfurther held in position by means of collars 71 and by ring members suchas 72 and 73 disposed at opposite sides thereof. One of the legs 70 isthreaded and engages with threads 74 on the shaft 54 at that point sothat as the shaft 54 is turned by the handle 57 the yoke member 68 ma)7be moved longitudinally and the shaft 14 thus turnedangulai-l)Y as willbe hereinafter explained. A eollar 75 fixed to shaft 54 between thevlegs (i9 and 70 will prevent ltoo much movement of the yoke member 68in either direction.

0 parat-i001.

lVith the parts in the position shown which can be-called a neutralposition we will assume that it is desired to adjust the second loadshaft so that it has a desired relative position respecting a certainoutside point. lhen it is desired to do this, the handle 67 is turned.This through the intermediary of the gear 65 will turn the box 27.' Theplate 44 being supported on the sleeve 62 of the box 27 will be moved inan arc along with the gear 52 and the shaft 51. The connection of theplate 44 with the sleeve 5() will cause the box 26 to rotate around itscenter and will cause the sleeve and the pin wheel shaft 30 to move inan arc with the axis of the box 26 as the center. This will tend to movethe shaft 33 and thereby enable it to be adjusted as desired.

As the box 27 is rotated around its center, the gear 52 which is fixedtherein will turn with the box and will roll along the teeth 53 on thecontrol shaft 54 slightly raising the control shaft as the plate 44is'slightly raised and lowered in its swinging motion. The connection ofthe control shaft 54 with the first load shaft 14 through the yoke 68will prevent the first load shaft from moving any Y substantial amountlongitudinally and will therefore cause the gear 37 to roll over theworm 38 as the pin wheel shaft 30 with the gear `37 is swung with thebox 26. Since the gears 52 and 37 are of the same diameter and have thesame arc of swing, the rolling movement of the gear 52 over the teeth 53will be exactly similar to the rolling movement of the gear 37 over theworm 38. Since the gear 52 is fixed to the box 27 and does not turnindependently thereof, it will be seen that the movement of the gear andthe pin wheel shaft will thus be with the box 26 and not vnot changedduring this adjustment. Alsol the first load shaft in its position andtime relation to the intermittent mechanism during the adjustment of thesecond load shaft is not changed. So the intersystem cyclic relationsare not changed during adjustment altho the extra-system cyclicrelations v of the second load shaft 33 are changed with regard to apoint outside the intermittent system.

When it is desired to turn the load shaft 14 to change the time positionthereof with respect to the other elements of the system, then itbecomes'necessary to turn the control shaft 54 through the intermediaryof the handle 57. This turning causes the movement of the yoke 68 bymeans of the threads '7 4. This longitudinal movement of the load shaft14 will cause the worm 38 to ride over the worm gear 37 and thisrelative motion will cause the worm 38 to turn slightly and this will cause the turning of the load shaft 14, the amount of the turning of thehandle 57 determining the amount to which the shutter shaft is turned asdesired.

"Thus the improved drive and adjusting device provides a simple anddirect connection between the first load shaft. and the pin wheel shaft.The p'in wheel shaft carries the Hy wheel and is swung around a definitearc with the load shaft. The first load shaft is prevented from turningduring this swinging movement by means of the control shaft which swingsin exactly the same arc and is connected to the first load shaft. Thepin wheel is prevented from turning with respect to the star wheel byforcing it with the gear 37 to roll over the first load shaft worm 38with a pure rolling action which is forced by the connection with thecontrol shaft the motion of which is controlled by the mesh between thegear 52 and the teeth 53.

A While the invention has been described in detail and with respect tothe present preferred form thereof, it is not -to be limited to suchdetails and forms since many changes and modifications may be made andthe invention embodied in other forms and modifications withoutdeparting from the spirit and scope of the invention in its broadestaspects.
